frontend-tools: Call modified prop callbacks on script load/reload

This change means that the modified callback for a scripts properties is
always called when first loaded or on a reload. This behavior matches
the properties view for sources, where all modified callbacks are called
when the window opens. This change therefore treats reloading as
equivalent to reopening.
